ABSTRACT OF THE DISCLOSURE Apparatus is provided for heating and extruding fluid sealant material onto a work surface which includes a heated feed chamber, a heated hose connected to the outlet of the feed chamber, and a handgun connected to the heated hose for applying the fluid sealant material onto the work surface. The feed chamber is provided with an opening for receiving sealant material in a solid bulk form and an outlet for dis- pensing sealant material in a fluid state. Heating coils are disposed on the outer walls of the feed chamber for heating the bulk sealant con- tained therein to a fluid state having a pumpable viscosity. The hose connected to the outlet of the feed chamber receives the fluid sealant material dispensed therefrom, and a heating coil surrounds the hose to maintain the sealant material passing therethrough In a fluid state. Within the feed chamber there is provided a rotatable screw conveyor feeding a positive displacement pump which may be driven at different rates to force fluid sealant material under high pressure into the heated hose so that the fluid sealant material is transmitted to the handgun under pressure. The heated handgun includes a removable nozzle which may be replaced to change the configuration of the sealant material which is extruded therefrom. A feedback arrangement is connected to the outlet of the positive displacement pump for retaining the fluid sealant material to the feed chamber when the pressure in the heated hose reaches a pre- determined level. This portable sealant applicator is capable of using bulk sealant, and is capable of extruding fluid sealant material through a lightweight portable hose extension.
